What is your favorite version of firefox? (not counting hardened)

LibreWolf

Firefox Focus on mobile with javascript disabled by default for news sites

The one that always ships late with my distro (Fedora) is my favorite, I guess, since it is the one I use :)

For Firefox mobile, it was the Fennec engine where you could easily install any extension... It became a pain with the Fenix engine

Android. It has the extensions I need and is plenty fast as well.

The gecko demo that fit on 1 3.5" floppy disk.

Old firefox XUL? When Add-ons isn't restricted.. Well old times.. When search toolbar Spyware are everywhere.. 😂

Iceraven on Android; it's got extensions I use -- notably SingleFile --- that the main Firefox doesn't have any more.
